DESCRIPTION OF EMBODIMENTS

(6) Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS. 1A and 1B. FIGS. 1A and 1B are each a perspective view illustrating an overall image when the foot is inserted. As shown in FIGS. 1A and 1B, a shoe body 1 according to an embodiment of the present invention is configured to include a shoe base part 5, an outer layer 2, sacs 3 mainly made of a stretchable material and an intake inlet/outlet 4.

(7) When the foot is inserted, an air-like gas is taken into the sacs 3 via an intake/discharge valve (not shown) of the intake inlet/outlet 4, and since the sacs 3 and the outer layer 2 are flexible, the shoe is configured to be stretched up to facilitate the insertion of the foot. FIG. 1A shows an example where the sacs 3 are spirally arranged and joined inside the outer layer 2. FIG. 1B shows an example where the doughnut-shaped sacs 3 are arranged and joined in a chained form.

(8) As described above, when the gas is taken in into the sacs 3, there can be various shapes into which the sacs 3 and the outer layer 2 are arranged so as to facilitate stretching out of the outer layer with flexibility, all of which are included in the inventive concept of the present invention.

(9) FIGS. 2A and 2B each are aa diagram illustrating when the easily wearable shoe according to the embodiment of the present invention is put on. In FIG. 2A, a gas is taken in into the sacs 3, and the sacs and the outer layer thereby acquire flexibility to stretch out the outer layer 2 and facilitate the insertion of a foot 6.

(10) FIG. 2B illustrates a case where the intake/discharge valve of the intake inlet/outlet 4 is loosened and the gas in the sacs 3 is discharged, and since the inner gas of the sacs 3 is discharged, the sacs 3 and the outer layer 2 contract and both come into close contact with the foot.

(11) That is, protrusions 7 are provided on a surface of the sacs 3 or a back (not shown) of the outer layer 2, and FIG. 3 shows an example of positions of the protrusions. FIG. 3 illustrates a nerve tissue 32 along a skeletal frame 31 of a foot 30 and the protrusions 7 are provided on the surfaces of the sacs or the back of the outer layer at positions corresponding to several acupuncture points 33 of the nerve tissue.

(12) The intake/discharge valve of the intake inlet/outlet 4 in FIGS. 1A and 1B is a check valve, but any type of valves may be used when a simple instrument is connected to or integrated with the shoe in advance to charge an air-like gas into the sacs 3, as long as the gas is never discharged and the sacs 3 which are mainly made of a stretchable material extend or contract caused by loosening of the valve, the sacs 3 are squeezed and the gas is discharged from the valve. However, the valve is preferably one that has a simple structure and is light-weighted.

(13) The intake inlet/outlet 4 provided with such a valve may be disposed at any position such as a vertex or side of the shoe body 1.

(14) Note that the intake inlet/outlet 4 and the intake/discharge valve may be integrally formed of a material having certain rigidity such as synthetic resin or metal or may be formed by combining parts generated using partially identical or different materials.

(15) As described so far, the easily wearable shoe according to the present invention takes in a gas into the sacs to thereby allow the foot to be inserted, loosens the intake/discharge valve of the intake inlet/outlet to discharge the gas, and can thereby cause the shoe to come into close contact with the foot. Furthermore, since the shoe according to the present invention fixes the foot to the shoe without using laces, it is possible to avoid disadvantages of the shoe having laces. Moreover, the structure with no laces can keep anti-air resistance high. Furthermore, these can be implemented with a relatively simple structure.

(16) Therefore, since no laces are used, the present invention can fully secure and take advantage of the functionality and ease of wearing with no possibility that laces may be untied, save time and effort required to retie the laces and convenience of taking-in/discharging the air from inside or outside the shoe. Furthermore, the air resistance can be significantly reduced compared to shoes with laces. Furthermore, it is possible to keep high convenience of taking-in/discharging the air from inside or outside the shoe. In addition, the shoe can be manufactured at low cost.

(17) FIG. 4 illustrates an example where positions of the outer layer 2 corresponding to the muscle, skeletal frame, blood vessel, nerve, meridian, reflexology, endocrine organ and other body organs of the foot are made of an extensible material such as a planar fastener 41 or adhesive tape. Of course, the planar fastener may be continuously attached.

(18) FIG. 5 is a perspective view of a shoe having a protector 51 attached for protecting the positions corresponding to the above-described body organs, the protector being attached to regions made of an extensible material such as the above-described planar fastener or adhesive tape. Moreover, the present invention can also be applied to a case where a disposable heating pad is added to a position of a necessary acupuncture point using the above-described planar fastener or the like to effectively prevent chilling of the foot or stimulate acupuncture points. Of course, by adding the planar fastener 41 to the shin of the foot as well, it is possible to attach a protector 52 or disposable heating pad to the part of the acupuncture point of the shin.

(19) Note that the present invention is not limited to the aforementioned embodiment, but various modifications, additions, substitutions, expansions, contractions or the like to the aforementioned embodiment are acceptable without departing from the identical or equivalent scope of technical ideas thereof. For example, those disposed in correspondence with the aforementioned muscle, skeletal frame, blood vessel, nerve, meridian, reflexology, endocrine organ and other body organs may be base parts widely associated with the structure of the shoe including the outer layer and/or inner sacs.

(20) Furthermore, for example, the technical idea of the present invention has been described above as the shoe as a single unit, but the present invention may also be implemented as a coating device in which these coating instruments are collectively formed, and the present application includes these embodiments as well.

INDUSTRIAL APPLICABILITY

(21) The easily wearable shoe according to the present invention allows the foot to be inserted quite simply, loosens the valve to remove the air to cause the shoe to instantaneously come into contact with the foot, thus making it possible to save time and effort required to tie or untie laces as shoes for senior citizens, significantly improve ease of use, reduce air resistance, and therefore the shoe according to the present invention is applicable to various sports fields and effectively applicable to various industries including the sports goods industry.

(22) Furthermore, since the structure is not complicated and configured of a relatively small number of parts, the shoe can be manufactured simply and at low cost, and can therefore be widely used in the field of all kinds of footwear or the like.

(23) Taking advantage of characteristics of ease of wearing through taking-in/discharging the air and the correspondence to body organs, which are the features of the present invention, the present invention can not only be applied to shoes but also be widely developed and applied to clothes and outfits.
